Every station and show should conduct a Zero-Based Programming analysis at least once per year (twice is better). It’s a big project, but the more you do it, the easier it gets. You can do it anytime, but summer (before the New Fall Season) and winter (before the new year) are the best times.
To help, use this powerful Zero-Based Programming Scoring Worksheet. It will keep you organized, focused, and help you execute your plan.
